Frequently Asked Questions

Can I watermark an image, not just a PDF?

Yes — this tool accepts both PDF documents and standalone image files.

How faint can I make the watermark?

Opacity is fully adjustable, from a bold, clearly visible stamp down to a subtle mark that barely interrupts the underlying content.
